Given
Amount of milk left after 3 operations = [ 40 (1 - 4 /40)^3 ] litres

159. A vessel is filled with liquid, 3 parts of which are water and 5 parts syrup. How much of the mixture must be drawn off and replaced with water so that the mixture may be half water and half syrup?

Correct Ans:1 / 5
Explanation:

Given Ratio of Water : Syrup = 3:5
Let's assume the volume of the vessel is 80 Litres.

Water = 30 Litres
Syrup = 50 Litres
Since all the liquid taken out of the vessel is replaced by water, the total volume remains constant.
Therefore, we need to ensure there's40 litresof water and Syrup individually.

Therefore, we need to take out10 litresof syrup and replace it with water.
For every8 litrestaken out of the vessel (Given Ratio of Water : Syrup = 3:5), we replace 5 litres of syrup with water.

Therefore, we need to replace16 litres, or 20%or 1/5th of the liquid from the vessel.

160. A 20 liters mixture of milk and water comprising 60% pure milk is mixed with "x" liters of pure milk. The new mixture comprises 80% milk. What is the value of "x"?

Correct Ans:20
Explanation:
Original mixture comprises 20 liters of milk and water.
Out of the 20 liters, 60% is pure milk. i.e., 12 liters is pure milk, remaining 8 liters is water.

When "x" liters of pure milk is added, we will have 12 + x liters of milk in the new mixture.
And there will be 20 + x liters of the new mixture.
The question also states that this (12 + x) liters of pure milk accounts

For 80% of (20 + x) liters of the mixture.
Therefore, 12 + x = (80/100) x (20 + x)
= (80 / 100) x ( 20+ x)
=> 20 litres.
Solving for x, we get x = 20 liters.
